SPECIFICATION forming part of Letters Patent No. 340,196, dated April 20, V1886..

Application tiled Jannary?, 1885.

To a/.ZZ whom it may concern,.-

Be it known that I, JOHN D. CURTIs,a citizen of the United States, residing at Worcester, in the county of Vorcester and State of Massachusetts, have invented certain new and usef'ul Improvements in Machines for Manufacturing Barbed Fencing; and I do hereby declare that the following is a full, clear, and exact description of the invention, which, in connection with the drawings, making a part of this specification, will enable others skilled in the art to which ,it appertains to make and use the same. Y 1

My invention relates to the manufacture of barbed fencing and to the automatic stopping of the barbing and the twisting and spooling machines in case of the improper working of said machines or either of them, in the manner to be hereinafter fully set forth.

`My present invention is designed to be used in connection with machines for manufacturing barbed fencing, in which the barbing and the twisting and spooling portions of the machines are operated independently of each other from separate counter-shafts and by separate beltconnection.

The following description, in connection with the drawings, describes and shows mechanism illustrating myinvention, and theclaims indicate the nature thereof.

Referring to the drawings, Figure l represents a top or plan view of a barbing-machine with mechanism applied thereto for carrying out my invention, as will be hereinafter fully described. 'Fig 2 represents a side view of the parts shown in Fig. l, looking in the direction of arrow a, same figure, the dott-ed lines representing parts of the stop mechanism in different positions. as will be hereinafter described; and Fig. 3 represents an end view oftheparts shown in Fig. l, looking in the direction ofarrow b, same figure. Fig. 4- represents a side view of a barbiug-niachine and of a portion ofa twistiugand spooling machine used in connection therewith and of the pulleys ou the counter-shafts and of the driving-belts and belt-shipping devices designed to be used in connection with my mechanism for automatically stopping the barbing and the twisting and spooling portions of the machine; and Fig. 5 is a plan view of the rocking lever- Serial No.151,748.

The construction and operation of machines for making barbed fencing, and of machines for twisting and spooling barbed fencing or plain wire fencing, are well known, and as my invention has no reference to any particu-Y lar style of machine, but is intended to be used in connection with any machine for making 6o barbed fencing, I have only shown in the drawings such parts of a barbing-machine as will be essential for the proper understanding of the carrying out of my invention--namely, the automatic stopping of the machines.

Similar letters of reference refer to similar parts in the drawings,

In the accompanying drawings, the part marked A is the top or bed of a barbingmachine, to which the several parts of the ma- 7o chine are secured inthe usual and well-known manner, B being the driving-shaft, turning in suitable bearings on the bed A, and operatedv in this instance by the driving wheel or pulley C,around which the drivingbelt C, passes, in the manner to behereinafter fully described.

D D are suitable rolls for feeding in the main wires; E, a suitable mechanism for feeding in the barb-wire, and F, a suitable barbing1nechanism, all constructed and operated in any 8o wel1known manner.

' The part marked T is the frame of the twister and spooler. U is the shaft for operating the twister and spooler, (not shown in the drawings) but of any usual and well-known con-v struction and operation, said shaft U turning in bearings a c ou the frame T, and having a pulley, b', secured thereto, around which the driving-'belt V passes.

The driving-belts C and V pass over pul` 9o leys c and d', secured upon conntershafts e and f. The counter-shafts e and f are driven by belt-connection with a main shaft. (Not shown in the drawings.) The driving-belts g and h', passing over pulleys z" and j, se- 95 cured upon said counter'shafts, and loose pulleys being placed upon said shafts next to the pulleys i and j', onto which the driving-belts g' and h are shipped to stop the barbing-machine and the twister and spooler, 'in the roo usual manner. y

I will now proceed to describe the mechanism shown in the drawings for automatically stopping the barbing-machine, and also the ,twisting and spooling machine.

small spring, c, secured to the rod H and themachine, holds the arm G against the barb, as shown, and also draws it back after it has beenpushed forward by the moving barb, as

- above stated. Upon the outer end of the rod H is a crank-arm, d, to which is secured a small connecting-rod, I, the other end of said rod I being pivoted to the sliding bar J, the outer end, e, of which is beveled and projects up, as shown'in Figs. l and 2. The sliding bar J moves in and out in the box or holder K, secured to the frame of the machine at the same time with and according to the movenient of the arm G, before described.

Upon the driving-shaft B is secured a collar, L. turning with said shaft, and having a slot. f, made in its outer surface.

The driving wheel orpulley C, around which the belt passes, is looso upon the drivingshaft B, being secured from working endwise on said shaft in any suitable and well-known manner.

Through the hub g of the driving-wheel C extends a movable driving-pin, M, its ends extending out on each side ofthe hub g, and a coiled spring, h, within the hub and around the,pi`n `M, keeps said pin in position and holds its end z', which is made with a projection extending out beyond the periphery of the collar L, (to strike against the end of the sliding bar JJ inthe slot f in said collar L, when the machine is in operation, causing the driving-shaft B to be revolved bythe drivingwheel C.

Upon the end of the driving-shaft B is a loose plate, N, secured from moving endwiseV on said shaft in any suitable and wellknown manner. Said plateN has a lug or projection, j, upon its inner side, against the side of which the end of the driving-pin M will strike when the said pin M is forced out of connection with the collar L, as will be hereinafter de'- scribed, and also a pin or arm, k, projecting ont therefrom, as shown in the drawlngs, for the purpose to be hereinafter stated.

In a suitable frame or support, l, at the rear of the harbing-machine, is hinged or pivoted an angle-arm', O, to the upper end of which is in this instance secured a cross-piece. m, wilh one or more guide-holesI a, through which the main wire or wires pass before entering the machine. To the other end of the anglearm O is secured a light coiled spring. o, the other end of said spring being Vsecured to the floor, as shown. The strain upon the main wires passing through'the guide-holes n in the cross-piece m (which are made a little larger than the wire) and the spring o serve to keep the angle-arm O in its proper position, as shown by full lines in the drawings.

In the frame l and supportp a shaft, P, is journaled to turn in suitable bearings. To one end of said shaft P is secured, to move with said shaft, an arm, Q, flattened at its end, and upon which the end of the Short arm of the angle-arm O rests when the parts of the stop mechanism are in their normal position, as shown by full lines in the drawings. To the arm Q is secured the cord or wire R,

the other end of said cord R being secured to what I call the rocking lever-holder W, supported upon a rod, k. Small collars lprevent the lever-holder W from moving endwise on said rod k', but allow it to move or rock up and down thereon. Against the project-ing ends m of the holderW the shippinglever arms a and o press, (see Figs. 4 and 5,) the lever n serving to ship the belt g', which drives the counter-shaft e of the barbing portion of the machine, and lhe lever o, through the pivoted connecting-arm p', the belt h, which drives the counter-shaft f of the twister and spooler. When the cord R is drawn down the lever-holder W is drawn up, allowing the levers n' and o to pass by the ends m thereof, springs g and i" servi ng to draw over the lever-arms n' and o', thus shipping onto the loose pulleys on the counter-shafts eand f the driving-belts g'and h', simultaneously, and stopping the machine.

To the other end of the shaft P is secured an arm, S, to move with said shaft P. The arm S is so placed that the end of the pin or arm k, projecting out from the plate N, willstrike against the underside of the endot the arm S when the plate N is revolved on the shaft B, raising up the arm S and causing the shaftP to turn, and the arm Q, projecting out from the shaft P in an opposite direction from the arm S, as shown in the drawings, to be drawn 4 down, thus shipping the belts by means of the cords R and stopping the machines, as will be hereinafter more fully explained.

The operation of the mechanism (for alitomatically'stopping the barbirig and the twisting and spooling machines) abovedescribed and shown in the drawings, is as follows:

The parts of the stop mechanism are in substantially the position shown by full lines in the drawings when a barb is being applied to or placed upon the main wire or wires, the arm G being held against the barb :c by the spring c. After the barb is placed upon the wire, and as it moves forward with the wire,

preparatory to another barb being placed on or applied to the wire, it carries or pushes the arm G forward in the are of a circle, allowing the barb to pass over the end of and by the arm G, as shown by dotted lines, Fig. 2. The arm G is then drawn back by thc spring c IIO against the next succeedingbarb, and the operation isrepcated as long as the barbs are placed upon the wire or wires -in a proper 'i ing in contact with the end t' of the driving-pin M, (which projects out from the periphery of the collar L, as before stated,) and allowing the driving-pin M to remain connected with the collar L, its end extending into the slot f in said collar L. and the machine to continue t i operate; but in case the arm G fails to be drawn forward, as above described, at the proper time, by reason of the failure of the placing of a barb upon the wire, or by reason ofthe strand, as it is twisted and spooled, acquiring too great a centrifugal force and iiying out of the twister and receiving-spool, and also out of contact with the arm G, the direct tension'on the strand being removed, or for any other reason,the sliding bar J is not drawn forward and its end e moved out of contact with the projecting end z' of the driving-pin M; but the end of the sliding bar J, striking against the end t' of the driving-pin M, forces said pin into the hub g of the driving-wheel C and out of the slot f in the collar L, thus disconnecting the driving-wheel C from the collar L on the driving-shaft B, and allowing said driving-wheel to turn loosely on said sh-aft. As the driving-pin M is moved into the hub g and disconnected with the collar L,in the manner above described, its outer end, y, as the wheel C revolves, will strike against the side of the lug j, extending out from the plate N, loose upon the driving-shaft B, and cause said plate to revolve or turn upon said shaft, and the pin or arm k, extending out from said plate N, to strike against the end of the arm S, secured to the shaft P, raising up said arm S and at the same time drawing down the arm Q, secured to the other end of said shaft I), (as shown by dotted lines, Fig. 2,) and the cord or cords R, causing the beits by which the barbing and the twisting and spooling machines are run to be shipped onto the loose pulleys on the counter-shaft,tl.ins disconnecting the driving-power and automatically stopping the machines simultaneously.

I have shown in the drawings and described an angle-lever arm, O, hinged at the rear end of the barbing-machine, and having one or more guide-holes, n, through which the main wires pass, before entering the barbing-machine; but I do not make any claim to the same, either alone or in combination with the other parts of my invention, in this application, for the reason that the same is included in a new application filed by me on the 18th day of November, 1885, Serial No. 183,177, and for the further reason that my present invention, as claimed by me, is a complete and operative invention without the anglelever arm O referred to.

The belt-shipping devices shown in Fig. 4 of the drawings are also included in said application No. 183,177, above referred to, in which the manner of their constructiomand the mode oftheir operation is described in greater detail; and I have therefore in this application only described them sufficiently to enable those skilled in the art to understand how the drivingdielts of the barbing and the twisting and spooling portions of the machine may be automatically and sinmltaneously shipped to stop the machine, said belt-shipping devices being operated by my automatic stop device applied tothe barbing portion ofthe machine.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1. A device placed in front of the barbing mechanism and in the path of the barbs, and connected with mechanism for disconnecting the driving-power of the barbing portion ofthe machine, in combination with mechanism for disconnecting the driving-power of the twisting and spooling portion of the machine, whereby when the first device fails to be operated in a proper manner the barbing and the twisting and spooling portions of the machin-e, which are operated independently of each other. will be automatically stopped, substantially as set forth.
